Suppose a particular species of tulip plant has four alleles for the gene that codes for flower color. The Tallele produces purple tulips, the T'allele produces red tulips, the t'allele produces orange tulips, and the tallele produces yellow tulips. These alleles have the following dominance hierarchy: T>T'>t>t. For a cross of T'Tx Tt, determine the expected purple: red : orange : yellow phenotypic ratio of offspring for flower color, (Due to limitations in the grading ability of this program,...

2. The color of fruit for plant "X" is determined by two alleles A and a. When two plants with orange fruits (Aa) are crossed the following phenotypic results are present in the offspring: 27 red fruit (AA), 59 orange fruit (Aa), 24 yellow fruit (aa). So you suspect this is an incomplete dominance case, which means the phenotypic ratio should follow 1:2:1 ratio. Using the data collected to test for this hypothesis....
15. The gene for petal color in a flower has incomplete dominance, so that individuals with two Al alleles (AIAI) are red, individuals with two A2 alleles (A2A2) are white, and individuals with one of each allele (A1A2) are pink. In a cross between a red flower and a white flower, what is the probability of getting a pink offspring? (2 points) In a cross between a red flower and a pink flower, what is the probability of getting a...
please answer two question below
thankyou
e) 9; 9 3. In another plant species, the presence and type of hairs on the plant are controlled by epistatic interaction between two independently assorting genes. Gene C determines whether the plant has hairs (dominant) or not (recessive); Rene D determines whether the hairs are straight (dominant) or curly (recessive). In a cross between a straight-haired plant and a curly- haired plant, 1/4 of the offspring have no hairs. 3/8 have straight hairs,...
II. MONOHYBRID PROBLEMS WITH INCOMPLETE DOMINANCE 8. Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype R R are red-flowered, those that are heterozygous (R W ) are pink, while those with the (WW ) genotype have white flowers. This is an example of incomplete dominance. a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1? __________________________________________________________ b. What...
Help Center 07 Question 38 What phenotypic ratio of offspring would result from a cross between a white-eyed male fruit fly, and a female that is heterozygous for red eye color? (See Chapter 8.3 Figure your e Text) 2 white-eyed females 2 red-eyed males V none of these 2 red-eyed female 1 white-eyed female: 1 red-eyed male: 2 white-eyed male 1 red-eyed female 1 white-eyed female 1 red-eyed male: 1 white-eyed male 2 red-eyed females: 2 white-eyed males Question 39...
0. In snapdragons, the alleles for flower color show incomplete dominance. CRCR produces red flowers; CWCW produces white flowers and CRCW produces pink flowers. The height of the plant is determined by a separate gene with regular dominant and recessive alleles. Normal height (D) is dominant over dwarf height (d). a. A snapdragon that is heterozygous normal in height and has white flowers is crossed with a plant that is dwarf in height and has red flowers. What is the...
In sweet peas, two genes (genes A and B) control flower color. The dominant alleles of both genes produce enzymes that function in the biochemical pathway shown to convert colorless precursors to a purple pigment. The recessive alleles do not produce enzyme. Therefore, at least one dominant allele of both gene A and gene B are required for purple flowers. Answer the questions about this biochemical pathway. ΑΑ, Αα BB, Bb Enzyme A Enzyme B Colorless precursor 1 Colorless precursor...

The flower color gene in snow peas has two alleles: P-Purple and p-white. The P allele codes for a protein that synthesizes purple pigment. How might the p allele be different such that it leads to white flowers? The p-allele could: (select all) a) produce a protein that cannot make pigment (true) b) lead to the gene being absent from flower cells (false) c) produce a protein that makes too much pigment (false) d) lead to the protein being absent...
